Abstract
In this paper, a compact, tri-band Planar Inverted-F Antenna (PIFA) using Complementary Split Ring Resonator (CSRR) and Reactive Impedance Surface (RIS) is presented for multiband application. The structure of the PIFA consists of a metallic CSRR and 5×6 periodic unit RIS cells, which accomplishes miniaturization and improves bandwidth and multiband. The RIS metamaterial plane lies between two substrates and acts as a loading function, reducing the volume of the antenna. The measured and simulated results are consistent for a manufactured prototype. The overall size of the antenna is 22.71×3.451×1mm. The PIFA shows a tri-band with an S11 < −10dB bandwidth of approximately 17.08% (2.26-2.67GHz), 5.14% (6.85-7.21GHz) and 19.44% (7.44-9.19GHz) under measurement. The antenna radiates a wave in a preset direction with realized gains ranging from 3.21 to 8.1dbi. The CSRR and RIS improve the performance of the antenna for WLAN, C-band, and X-band applications.
Highlights
With the rapid advancement of wireless applications, lightweight, low-cost, and often omnidirectional radiation pattern antennas are becoming increasingly popular

Polarization, gain, Voltage Standing Wave Ratio (VSWR), and return loss of the PIFA antenna were measured in a Vector Network Analyzer (VNA)
Summary
With the rapid advancement of wireless applications, lightweight, low-cost, and often omnidirectional radiation pattern antennas are becoming increasingly popular. A dual-band operation is addressed by loading an electrically small CSRR structure in [7]. A tri-band antenna was presented in [9] and a CSRR loaded multiple-input–multiple-output antenna with electrically small elements and reduced mutual coupling in [10]. A loop antenna loaded with a Coplanar Strip (CPS) line was added along with two switches that allow the antenna perimeter to be varied to cover 7 different bands [23]. The CPS line is combined with two switches to vary the antenna perimeter to cover 7 different bands, and an Artificial Magnetic Conductor (AMC) was used as the reflector plane in [24]. The PIFA is a built-in mobile antenna that compensates for polarization issues, narrow bandwidth, lower gain, and operates multiple frequency bands
